1 Claim. (Cl. 6515) This invention relates to non-skid dishes.

It is an object of the present invention to provide dishes havingprojections thereon adapted to engage the supporting surfaces in amanner that they will not readily skid from such surfaces when used onships at sea or air liners.

It is another object of the invention to provide on dishes projectionswhich will not only serve to prevent the skidding of dishes uponsurfaces, but which will make easy the drying of the dishes on thedrying racks due to the air gap permitted under the dish upon thesedishes with the projections being stacked in abutment with each other onthe drying racks.

It is another object of the invention to provide dishes with a non-skiddevice which is adjustable to present either a smooth material or inanother position rubber so as to provide further friction when necessaryto keep the dishes from skidding and wherein the adjustment of theseelements can be readily and easily effected and with the rubber portionhaving an undercut opening to provide a vacuum type tight grip upon thesupporting surface.

Other objects of the invention are to provide a nonskid dish for use onships at sea and on air liners, which is of simple construction,inexpensive to manufacture, has a minimum number of parts, compact,durable, sanitary and easy to clean and eflicient and effective in use.

For other object and a better understanding of the invention referencemay be had to the following detailed description taken in connectionwith the accompanying drawing, in which:

Figure 1 is a collective and perspective view of a cup and a saucerhaving projections respectively thereon to prevent the skidding of thesaucer or cup upon the surface on which either of them is rested;

Fig. 2 is a sectional view of an ash tray having projections on thebottom of the same to prevent the skidding of the same over thesupporting surface;

Fig. 3 is a fragmentary perspective view of a pointed form ofprojection;

Fig. 4 is a fragmentary perspective view of a still further form ofprojection of truncated formation;

Fig. 5 is a perspective view of a still further form of projection andof pyramidal shape;

Fig. 6 is a fragmentary elevational view of a pitcher having a stillfurther form of projection on the bottom of the pitcher and which isadjustable to present either a rubber vacuum cup surface or a smoothrounded surface;

Fig. 7 is an enlarged fragmentary sectional view of the projectionadjusted to present a smooth surface for engagement with a supportingtable surface;

Fig. 8 is a fragmentary projection in sectional view of the ball rotatedto present the rubber vacuum cup connection with the surface in orderthat the pitcher can cling to an inclined supporting surface.

Referring now to the figures and in particular to Fig. 1, 10 representsa cup having a bottom 11 and a handle 12. On the bottom 11 are threedepending projections 2,750,769 Patented June 19, 1956 13circumferentially spaced about the periphery of the bottom 11 and ofrough surface to prevent the cup from sliding on a smooth supportingsurface or in a saucer 14. This saucer may have similar projections 15on the bottom thereof for engagement with the table surface. Theprojections 13 will engage the interior of the saucer 14 and will tendto prevent the movement of the cup within the saucer and the projections15 will engage a smooth table or supporting surface in such a manner asto prevent the sliding of the saucer upon the surface. The ends of theprojection can be left unfinished and have a ceramic or soft engagingsurface, or, if desired, the ends of the projections can be frosted.Also, the projections can have sand or grit upon the same to make themrough.

In Fig. 2 there is shown an ash tray having the usual indentations onthe flange as indicated at 16. This ash tray is indicated generally at17 and has a bottom 18 thereon with projections 19 constructed similarto the projections 13 and 15 in the form of the invention shown inFig. 1. These projections are similarly roughened to prevent slipping orskidding of the ash tray upon the surface upon which the ash tray issupported.

In Fig. 3, there is shown a different form of projection. The projectionis simply pointed to provide a sharp point to engage a wood or roughtable supporting surface. This sharp point is indicated at 20 and issuch as to positively prevent the sliding of the dish on the tablesurface.

In Fig. 4, there is shown a truncated projection 21 having a flat bottomsurface 22 which is roughened or left unfinished as explained above soas to have a large area of engagement with the supporting surface. InFig. 5 there is shown a still further form of projection which issimilar to the projection 20 of Fig. 3, and as indicated at 23 is ofpyramidal configuration having a sharp pointed end for engagement withthe supporting surface.

Referring now to Figs. 6, 7 and 8, there is shown a still further formof the invention. According to this form of the invention there isprovided a pitcher 25 having a bottom 26 having a plurality of socketsdisposed there on as indicated at 27 with rotatable or adjustable balls28 disposed respectively for adjustment in the respective socketformations.

Each ball 28 has a half rubber portion 29 with a vacuum cup 31 therein.This rubber portion has a portion 32 dovetailed to the rubber portion29, as indicated at 33, and which is smooth to permit the easy use ofthe pitcher 25 when the table surface is steady and motionless. Duringrough weather upon ships at sea or in airplanes, this ball 28 can beadjusted to the position shown in Fig. 8 from the position shown in Fig.7, in the manner illustrated by the finger so that the rubber portion 29and the vacuum cup formation thereof will engage the supporting surface.It will be apparent that upon the supporting surface being inclined thevacuum cup formation and the rubber will hold the pitcher againstsliding movement, and thus prevent the pitcher from dropping to thefloor from the table during any shifting or departure of the tablesurface from its usual horizontal position. During calm weather at sea,the ball 28 can be shifted back to the position shown in Fig. 7. Theportion 32 having the smooth surface can be made of wood, ivory, ceramicor plastic material. This smooth portion 27 is exposed normally as itoffers smoother handling of the chinaware, but in stormy weather aboardship, the rubber side containing a suction cup is used.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.
